摘要

The invention relates to a device (1) and a method for delivering a fluid, in particular hot-melt adhesive, comprising a base member (5) having an inlet opening (2) for receiving the fluid from a fluid source and an outlet opening for delivering the fluid to a nozzle arrangement (7), a nozzle arrangement (7) which is associated with the base member (5) and which has a discharge passage with a discharge opening (9) for delivery of the fluid, and a heat transfer means (3) for heating or cooling the fluid, having a heat transfer passage (14) through which the fluid can flow. The invention is characterized in that the heat transfer passage (14) is of a flow cross-section which changes in the flow direction.
